SPECIFICATION forming part of Letters Patent No. 744,400, dated November1'7", 1903. Application filed August 29,1903. Serial No. 171,218. (Nomodel.)

To all whom it may concern:

Be it known that 1, JOHN PLAYER, of Dunkirk, in the county ofChautauqua. and State ofNewYork, have inventedacertain new and usefulImprovement in Locomotive-Frames, of which improvement the following isa specification. I

The object of my invention is to simplify, economize, and strengthentheconstruction of the front ends of the frames of locomotiveengines by theprovision of means whereby the side frame members may be firmlyconnected one to the other and to the cylindersaddles and buffer-beamwithout necessitating the splices ordinarily employed in the main framebetween the cylinders and the front pedestals or involving the objectionof integral front end extensions of. the main frame, which require thewhole frame to be taken down in the event of damage at the front end. l

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view, in elevation, ofthe forward portion of a locomotive-engine, illustrating. an applicationof my invention; Fig. 2, a plan or top view, on an enlarged scale, ofthe bumperbracke't; and Fig. 3, a side view in elevation of the same.

' My invention is herein exemplified as ap-V plied in alocomotive-engine, the front end of the boiler 4 of which is supportedupon cylinder-saddles 12 of the ordinary construction, upon the lowerend portions of which the cylinders 12 are formed, and which abut ontheir inner sidesand are connected at top to the smoke-box 4 of theboiler, which is supported upon them, and at theirlower outer sides tothe side frame members 8 in the usual or any preferred manner.

In lieu of employing separate front framesections and splicing them tothe main side frame members 8, between the front pedestals 8 and thecylinder, or of extending the side frame members integrally toconnections with the buffer-beam, both of which plans have heretoforebeen adopted in practice, the side frame members 8 are under myinvention extended without connected front bars or sections from thefront pedestals to a transverse plane which is only slightly in advanceof the cylinder-saddles-that is to say, only so far as will admit of asufficient amount of metal to properly back up the lugs 8, which formbearings for the keys 8 which are employed in the connection of the saddownwardly-extending flanges 6O on its sides and a downwardly-extendingand laterallyprojecting flange on its forward end, to which thebuffer-beam 8 is secured by bolts 60, thus dispensing with the heavyplate which is ordinarily placed behind the bufferbeam. Longitudinallateral extensions 60, which are downwardly flanged, project rearwardlyfrom the body-plate 60. The outer faces of the flanges of saidextensions are trued off and abut against the side frame members 8 andare perforated with horizontal bolt-holes 60 for the reception of bolts60, by which the bu mper-bracket is connected to the forward portions ofthe side frame members. Vertical bolt-holes 6O are also formed in therear extensions 60 and in the adjoining rear end of the body of thebumpercasting for the reception of bolts, by which the latter isconnected to the bottoms of the cylinder-saddles 12. The body-plate ofthe bum per-casting is strengthened and stifiened by ribs 6O and therear extensions by ribs 60. portion of the body-plate, to which areconnected smoke-box braces 60 the upper ends of which are secured to thesmoke-box 4, thus further supporting the bumper-bracket to resistshocks. Where a two-wheeled leading-truck is employed, as is indicatedin the instance herein exemplified, a spindle-guide 60 is formed uponthe body-plate.

It will be seen that under the above construction the cylinder-saddlesand side frame members are firmly secured together and their connectionto the buffer-beam efiected by a single member,which is thoroughlysupported and braced, and, further, that the expense and inconvenienceof separate front frame- Lugs 60 are formed upon the forward 3 bars orforward extensions of the main frame members to the buffer-beam arewholly obviated. It will also be obvious to those skilled inlocomotive-engine construction that while my improvement is herein setforth as applied in connection with cylinder-saddles, each of whichcarries a cylinder and forms the half of a bed-plate intermediatebetween the cylinders, it is equally applicable where a centralbed-plate and separate cylindersconnected to the sides thereof areemployed, as is practiced in some cases, said single central bed-platebeing the recognized mechanical equivalent of two centrally-connectedcylinder-saddles.

I claim as my invention and desire to secure by Letters Patent 1. In alocomotive-frame, the combination of cylinder-saddles, two side framemembers which extend integrally from the front pedestals to the front ofthe cylinder-saddles, a buEer-beam, and a bumper-casting interposedbetween and constituting the longitudinal connection of the side framemembers and the buffer-beam.

2. In a locomotive-frame, the combination of cylinder-saddles, two sideframe members which extend integrally from the front pedestals to thefront of the cylinder-saddles, a buffer-beam, and abumper-castinginterposed between the side frame members and thebuffer-beam and secured at its rear to the side frame members andcylinder-saddles and at its front to the buffer-beam.

3. In a locomotive-frame, the combination of cylinder-saddles, two sideframe members which extend integrally from the front pedestals to thefront of the cylinder-saddles, a bufier-beam, and a bumper-castinghaving rearward extensions which are interposed between and secured tothe side frame members and are also secured to the cylinder-saddles,

and a transverse front flange which is secured to the buffer-beam.

4. In a locomotive-frame, the combination of cylinder-saddles, asmoke-box supported on and secured thereto, two side frame members whichextend from the front pedestals to the front of the cylinder-saddles, abufferbeam, a bumper-casting interposed between the side frame membersand the buffer-beam and secured at its rear to the side frame membersand cylinder-saddles and at its front to the buflfer-beam, and bracesconnecting the bu mper-casting to the smoke-box.

5. A bu mper-casting for locomotive-frames comprisinga ribbed platehavingdownwardlyextending flanges on its sides, a downwardlyextendingand laterally-projecting flange on its forward end for connection to abufferbeam, and rearward downwardly-flanged lateral extensions inposition to abut vertically against side frame members and horizontallyagainst cylinder-saddles.

6. A bumper-casting for locomotive-frames comprising a ribbed platehavingdownwardlyextending flanges on its sides, a downwardlyextendingand laterally-projecting flange on its forward end for connection to abufferbeam, rearward downwardly-flanged lateral extensions in positionto abut vertically against side frame members and horizontally againstcylinder-saddles, and lugs on the upper portion of its body forconnection to smoke-box braces.
